Try getting anywhere between the hours of 4 p.m. and 6 p.m. and you're all but sure to shake your head in disgust, muttering, "What are you doing?" to your fellow motorists.

One man gunning for the Oregon governor's mansion claims an amusement park attraction might be the answer, at least on the Interstate Bridge. Democratic candidate Dave Stauffer over the weekend unveiled his idea to erect a 30-story parking garage in Vancouver that would deliver its users to downtown Portland via water slide.

That's right: A water slide. (With skiffs, of course.)

"It's a lighter structure because it's made of plastic," he says in the announcement video. "It doesn't have to be heavy enough to support cars and trucks."

Stauffer likens the delivery method to Space Mountain, except here riders will carry "briefcases and cellphones and then they'll ride all the way into downtown Portland."

The icing on the cake is the illustration that Stauffer either created or commissioned of what this slide would look like.

The beauty of the plan, Stauffer says, is that there are plenty of tall buildings in Portland where the skiffs can dock, which means they won't compete with cars on the street for that precious, precious parking space.

"They won't have to stop for stoplights. The skiffs will go into downtown Portland, almost a straight shot," he says. "If you go off the top of a 30-story parking structure, you will probably accelerate to somewhere around 80 to 100 mph."
